Preparations for Next Moonwalk Simulations Underway (and Underwater)
Eric Garza, an engineering technician in the Experimental Fabrication Shop at NASA’s Armstrong Flight Research Center in Edwards, California, cuts plywood to size for temporary floorboards for the X-66 experimental demonstrator aircraft on Aug. 26, 2024.NASA/Steve Freeman NASA designed temporary floorboards for the MD-90 aircraft to use while it is transformed into the X-66 experimental demonstrator aircraft. These floorboards will protect the original flooring and streamline the modification process.
Supporting the agency’s Sustainable Flight Demonstrator project, a small team in the Experimental Fabrication Shop at NASA’s Armstrong Flight Research Center in Edwards, California, built temporary floorboards to save the project time and resources. Repeated removal and installation of the original flooring during the modification process was time-consuming. Using temporary panels also ensures the original floorboards are protected and remain flightworthy for when modifications are complete, and the original flooring is reinstalled.
“The task of creating the temporary floorboards for the MD-90 involves a meticulous process aimed at facilitating modifications while maintaining safety and efficiency. The need for these temporary floorboards arises from the detailed procedure required to remove and reinstall the Original Equipment Manufacturer (OEM) floorboards,” said Jason Nelson, experimental fabrication lead. He is one of two members of the fabrication team – one engineering technician and one inspector – manufacturing about 50 temporary floorboards, which range in size from 20 inches by 36 inches to 42 inches by 75 inches.
A wood router cuts precise holes in plywood for temporary floorboards on Aug. 26, 2024, in the Experimental Fabrication Shop at NASA’s Armstrong Flight Research Center in Edwards, California. The flooring was designed for the X-66 experimental demonstrator aircraft. NASA/Steve Freeman Nelson continued, “Since these OEM boards will be removed and reinstalled multiple times to accommodate necessary modifications, the temporary floorboards will save the team valuable time and resources. They will also provide the same level of safety and strength as the OEM boards, ensuring that the process runs smoothly without compromising quality.”
Designing and prototyping the flooring was a meticulous process, but the temporary solution plays a crucial role in optimizing time and resources as NASA works to advance safe and efficient air travel. The agency’s Sustainable Flight Demonstrator project seeks to inform the next generation of single-aisle airliners, the most common aircraft in commercial aviation fleets around the world. NASA partnered with Boeing to develop the X-66 experimental demonstrator aircraft.
NASA Armstrong’s Experimental Fabrication Shop carries out modifications and repair work on aircraft, ranging from the creation of something as small as an aluminum bracket to modifying wing spars, fuselage ribs, control surfaces, and other tasks to support missions.

Rebecca Mataya is a budget analyst at NASA’s Stennis Space Center. “Whether you are an engineer, analyst, lawyer, technician, communicator or innovator, there is a place for you here at NASA,” she said. “Every skill contributes to the greater mission of pushing the boundaries of exploration, discovery, and progress. If you have a passion, determination, and willingness to learn, NASA is a place where you can grow and leave a lasting impact on the future of space.”NASA/Stennis A career path can unfold in unexpected ways. Ask NASA’s Rebecca Mataya.
The journey to NASA’s Stennis Space Center near Bay St. Louis, Mississippi, was not planned but “meant to be,” she said.
While working for a local business, the Picayune, Mississippi, native frequently delivered items to NASA Stennis. While making a delivery, Mataya noticed a construction worker who needed directions while waiting to receive a NASA Stennis visitor’s badge.
“I stepped in by offering a map and highlighting the way,” Mataya said.
This small moment of initiative caught the attention of the receptionist, who mentioned an opening at NASA Stennis. She noted that Mataya’s approach to the situation displayed the NASA Stennis culture of hospitality and a can-do attitude.
“The rest is history,” she said. “Looking back, it was not just about finding a job – it was about NASA Stennis finding me, and me discovering a place where I would build a fulfilling career.”
Since the first day of work when Mataya walked into NASA Stennis “in complete awe,” she has felt like every day is a learning experience filled with “wow” moments, like seeing a test stand up close and meeting rocket engineers.
The Carriere, Mississippi, resident worked as a support contractor from 2008 to 2022, filling various roles from lead security support specialist to technical writer and program manager.
Her career path has progressed, where each role built upon the previous.
As a budget analyst in the NASA Stennis Office of the Chief Financial Officer since 2022, Mataya oversees the planning, programing, budgeting, and execution of funds for all Office of Strategic Infrastructure work within the NASA Stennis Center Operations Directorate. She also manages budgets for the NASA Stennis Construction of Facilities projects, and the congressionally approved Supplemental Funding portfolio.
“It is a role that requires adaptability, strategic thinking, and financial oversight,” she said. “I have cultivated these skills through years of experience, but more than that, it is a role that allows me to contribute something meaningful to the future of NASA and space exploration.”
Mataya will complete a master’s degree in Business Administration from Mississippi State University in May. She previously earned her bachelor’s degree from Mississippi State and an associate degree from Pearl River Community College.
“My career has been shaped by growth and achievement, but the greatest highlight has always been the incredible people I have had the privilege of working with,” she said. “Walking the halls of NASA, where top leaders recognize me by name, is a testament to the trust and relationships I have built over the years.”
Mataya said supervisors have consistently entrusted her with more complex projects, confident in her ability to rise to the challenge and deliver results. As a result, she has had opportunities to mentor interns and early-career professionals, guiding them as others once guided her.
“Seeing my colleagues succeed and knowing they have reached their goals, and championing their progress along the way, remains one of the most rewarding aspects of my career,” she said.
Mataya knows from experience that NASA Stennis offers opportunity and a supportive environment, not only for employees looking for career growth, but to customers seeking world-class testing facilities. “NASA Stennis is a place where collaboration thrives,” she said. “It is where NASA, tenants, and commercial partners come together as one cohesive community with a culture of mutual respect, support, and an unwavering commitment to excellence. As America’s largest rocket propulsion test site, NASA Stennis is evolving, and I look forward to seeing how our technological advancements attract new commercial partners and expand NASA’s capabilities.”

From left to right, NASA Marshall engineers Carlos Diaz and John Luke Bili, U.S. Naval Research Laboratory mechanical engineer contractor Eloise Stump, and Marshall engineers Tomasz Liz, David Banks, and Elise Doan observe StarBurst in the cleanroom environment before it’s unboxed from its shipping container. The cleanroom environment at Marshall is designed to minimize contamination and protect the observatory’s sensitive instruments. Image Credit: NASA /Daniel Kocevski StarBurst, a wide-field gamma ray observatory, arrived at NASA’s Marshall Space Flight Center in Huntsville, Alabama, March 4 for environmental testing and final instrument integration. The instrument is designed to detect the initial emission of short gamma-ray bursts, a key electromagnetic indicator of neutron star mergers.
“Gamma-ray bursts are among the most powerful explosions in the universe, and they serve as cosmic beacons that help us understand extreme physics, including black hole formation and the behavior of matter under extreme conditions,” said Dr. Daniel Kocevski, principal investigator of the StarBurst mission at NASA Marshall.
According to Kocevski, neutron star mergers are particularly exciting because they produce gamma-ray bursts and gravitational waves, meaning scientists can study these events using two different signals – light and ripples in space time.

The Naval Research Lab transferred the instrument to NASA in early March.Image Credit: NASA/Davy Haynes The merging of neutron stars forges heavy elements such as gold and platinum, revealing the origins of some of Earth’s building blocks.
“By studying these gamma-ray bursts and the neutron star mergers that produce them, we gain insights into fundamental physics, the origins of elements, and even the expansion of the universe,” Kocevski said. “Neutron star mergers and gamma-ray bursts are nature’s laboratories for testing our understanding of the cosmos.”
StarBurst will undergo flight vibration and thermal vacuum testing at Marshall in the Sunspot Thermal Vacuum Testing Facility. These tests ensure it can survive the rigors of launch and harsh environment of space.
Final instrument integration will happen in the Stray Light Facility, which is a specialized environment to help identify and reduce unwanted light in certain areas of the optical systems.
The StarBurst Multimessenger Pioneer is a wide-field gamma-ray observatory designed to detect the initial emission of short gamma-ray bursts, important electromagnetic indicators of neutron star mergers. With an effective area over five times that of the Fermi Gamma-ray Burst Monitor and complete visibility of the unobscured sky, StarBurst will conduct sensitive observations. NASA/Daniel Kocevski StarBurst is a collaborative effort led by NASA’s Marshall Space Flight Center, with partnerships with the U.S. Naval Research Laboratory, the University of Alabama Huntsville, the Universities Space Research Association, and the UTIAS Space Flight Laboratory. StarBurst was selected for development as part of the NASA Astrophysics Pioneers program, which supports lower-cost, smaller hardware missions to conduct compelling astrophysics science.

X-ray: NASA/CXC/Technion/N. Keshet et al.; Illustration: NASA/CXC/SAO/M. Weiss People often think about archaeology happening deep in jungles or inside ancient pyramids. However, a team of astronomers has shown that they can use stars and the remains they leave behind to conduct a special kind of archaeology in space.
Mining data from NASA’s Chandra X-ray Observatory, the team of astronomers studied the relics that one star left behind after it exploded. This “supernova archaeology” uncovered important clues about a star that self-destructed – probably more than a million years ago.
Today, the system called GRO J1655-40 contains a black hole with nearly seven times the mass of the Sun and a star with about half as much mass. However, this was not always the case.
Originally GRO J1655-40 had two shining stars. The more massive of the two stars, however, burned through all of its nuclear fuel and then exploded in what astronomers call a supernova. The debris from the destroyed star then rained onto the companion star in orbit around it, as shown in the artist’s concept.
This artist’s impression shows the effects of the collapse and supernova explosion of a massive star. A black hole (right) was formed in the collapse and debris from the supernova explosion is raining down onto a companion star (left), polluting its atmosphere.CXC/SAO/M. Weiss With its outer layers expelled, including some striking its neighbor, the rest of the exploded star collapsed onto itself and formed the black hole that exists today. The separation between the black hole and its companion would have shrunk over time because of energy being lost from the system, mainly through the production of gravitational waves. When the separation became small enough, the black hole, with its strong gravitational pull, began pulling matter from its companion, wrenching back some of the material its exploded parent star originally deposited.
While most of this material sank into the black hole, a small amount of it fell into a disk that orbits around the black hole. Through the effects of powerful magnetic fields and friction in the disk, material is being sent out into interstellar space in the form of powerful winds.
This is where the X-ray archaeological hunt enters the story. Astronomers used Chandra to observe the GRO J1655-40 system in 2005 when it was particularly bright in X-rays. Chandra detected signatures of individual elements found in the black hole’s winds by getting detailed spectra – giving X-ray brightness at different wavelengths – embedded in the X-ray light. Some of these elements are highlighted in the spectrum shown in the inset.
The team of astronomers digging through the Chandra data were able to reconstruct key physical characteristics of the star that exploded from the clues imprinted in the X-ray light by comparing the spectra with computer models of stars that explode as supernovae. They discovered that, based on the amounts of 18 different elements in the wind, the long-gone star destroyed in the supernova was about 25 times the mass of the Sun, and was much richer in elements heavier than helium in comparison with the Sun.
This analysis paves the way for more supernova archaeology studies using other outbursts of double star systems.
A paper describing these results titled “Supernova Archaeology with X-Ray Binary Winds: The Case of GRO J1655−40” was published in The Astrophysical Journal in May 2024. The authors of this study are Noa Keshet (Technion — Israel Institute of Technology), Ehud Behar (Technion), and Timothy Kallman (NASA’s Goddard Space Flight Center).
NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

Visual Description
This release features an artist’s rendering of a supernova explosion, inset with a spectrum graph.
The artist’s illustration features a star and a black hole in a system called GRO J1655-40. Here, the black hole is represented by a black sphere to our upper right of center. The star is represented by a bright yellow sphere to our lower left of center. In this illustration, the artist captures the immensely powerful supernova as a black hole is created from the collapse of a massive star, with an intense burst of blurred beams radiating from the black sphere. The blurred beams of red, orange, and yellow light show debris from the supernova streaking across the entire image in rippling waves. These beams rain debris on the bright yellow star.
When astronomers used the Chandra X-ray Observatory to observe the system in 2005, they detected signatures of individual elements embedded in the X-ray light. Some of those elements are highlighted in the spectrum graph shown in the inset, positioned at our upper lefthand corner.
The graph’s vertical axis, on our left, indicates X-ray brightness from 0.0 up to 0.7 in intensity units. The horizontal axis, at the bottom of the graph, indicates Wavelength from 6 to 12 in units of Angstroms. On the graph, a tight zigzagging line begins near the top of the vertical axis, and slopes down toward the far end of the horizontal axis. The sharp dips show wavelengths where the light has been absorbed by different elements, decreasing the X-ray brightness. Some of the elements causing these dips have been labeled, including Silicon, Magnesium, Iron, Nickel, Neon, and Cobalt.
